http://www.lightningmaps.org/extra/coverage?lang=en http://www.lightningmaps.org/extra/coverage?lang=en As mentioned by mnw, coverage is actually pretty sparse in North America (at least relative to Europe, presumably because it's a German project?). The continent simply has environments that are ideal for severe thunderstorms. I imagine the other continents are grossly underrepresented.
